Formatting computer response ASAP please

I am trying to format my pc it wont let me format by right clicking on the C: drive so i tried to format by booting from CD Boot i change the boot sequence. it started to load the settings then it restarts the computer when loading the keyboard layout. Any ideas why please help

yer i am thats the only way it will let me do it. have tried to use computer managment to do it but it still wont let me. i would rather just format the computer it looks like i will have to just reinstall.

ok, try rebooting the computer and entering BIOS at setup this can be different depending on what computer you have but typically its F1,F2 or DEL most commonly. Once there use the arrow keys to go over to Boot Sequence or Boot Order and hit ENTER. Use the down arrow key to select the drive that the CD is in and press enter. Then hit F10 to save and exit the computer will automatically reboot and hopefully take you to the Welcome to setup screen.

This is different then just changing the boot order using a key like F8 before the boot screen

are you sure it could be this bcoz it has been sent to pl to get it fixed and they have been able to do it.
ut also are XP disk is a copy bcoz we copied it just incase it broke n it did this has been used b4 could this have anything to do with it.

Ok, go into BIOS and change the boot order back, I want you to boot off the hard drive, but right before windows starts to load tap f8 repeatedly. If it asks where to boot from select your hard drive then continue tapping f8 until a menu pops up.

ok, this may take a while, but it will repair any errors on your hard disk and check for bad sectors. After this is complete see if your computer is preforming better and we should also consider checking for malware, unfortunately I don't think that your XP CD is bootable. If you have tried to let it restart a few times and still cant get it to load welcome screen.
